A stroke occurs when a blood vessel in the brain is blocked or bursts. Without blood and the oxygen it carries, part of the brain starts to die. The part of the body controlled by the damaged area of the brain can't work properly.
Brain damage can begin within minutes, so it is important to know the symptoms of stroke and act fast. Quick treatment can help limit damage to the brain and increase the chance of a full recovery.
What are the symptoms? Symptoms of a stroke happen quickly. A stroke may cause:
· Sudden numbness, tingling, weakness, or paralysis in your face, arm, or leg, especially on only one side of your body.
· Sudden vision changes.
· Sudden trouble speaking.
· Sudden confusion or trouble understanding simple statements.
· Sudden problems with walking or balance.
· A sudden, severe headache that is different from past headaches.
If you have any of these symptoms, call911or other emergency services right away.
See your doctor if you have symptoms that seem like a stroke, even if they go away quickly. You may have had a transient ischemic attack (TIA), sometimes called a mini-stroke. A TIA is a warning that a stroke may happen soon. Getting early treatment for a TIA can help prevent a stroke.
